A new coumarin-based fluorescent probe, containing an allylic esters group, has been designed and synthesized for sensing cysteine in physiological pH. In this fluorescent probe, the coumarin was applied as the fluorophore and an allylic esters group was combined as both a fluorescence quencher and a recognition unit. The probe can selectively and sensitively detect cysteine (Cys) over homocyst...

A colorimetric and fluorescent dual probe for palladium species was rationally developed by combining the resorufin fluorophore with allyl chloroformate. The probe enables the visual detection of palladium based on its vivid color change from pale yellow to pink and its fluorescence off-on response to palladium in PBS solution. The detection limit was calculated to be as low as 2.1 nM. The live...

Correction for ‘A lipid droplet targeted fluorescent probe high-efficiency image-guided photodynamic therapy of renal cell carcinoma’ by Ping Tan et al., Chem. Commun., 2021, DOI: 10.1039/d0cc07336a.

A fluorescent molecular rotor is exploited as a viscosity probe to reveal heterogeneity in multi-material microstructures made by two-photon polymerization. These results open the door 4D character of active 3D microstructures.

Based on chelation-enhanced fluorescence, a new fluorescent coumarin derivative probe 3(1-(7-hydroxy-4-methylcoumarin)ethylidene)hydrazinecarbodithioate for Hg(2+), Ag(+) and Ag nanoparticles is reported. Fluorescent probe acts as a rapid and highly selective "off-on" fluorescent probe and fluorescence enhancement by factors 5 to 12 times was observed upon selective complexation with Hg(2+), Ag...

background: acute promyelocytic leukemia (apl) is a subclass of acute myeloid leukemia. the chromosomal aberration in 95% of apl cases is t(15; 17) (q22; q21), which prevents cell differentiation. characterization of the underlying molecular lesion is valuable in determining optimal treatment strategy. the goal of this study was to develop a new and powerful flow- fish technique to detect the l...

The development of novel selective probes with high sensitivity for the detection of Al(3+) is widely considered an important research goal due to the importance of such probes in medicine, living systems and the environment. Here, we describe a new fluorescent probe, N'-(4-diethylamino-2-hydroxybenzylidene)-2-hydroxybenzohydrazide (1), for Al(3+). Probe 1 was evaluated in a solution of acetoni...

We have constructed a novel NIR fluorescent turn-on hydrogen sulfide probe suitable for fluorescent imaging in living cells based on thiolysis of dinitrophenyl ether.
